Interface Summary

BooleanExpr
CloneableNodeIterator
ExprContext	packages up the context available to the XSLT engine when evaluating XPath expressions
ExtensionContext
Function	all functions have the method: "makeCallExpr( ...
NameExpr
NodeSetExpr	A NodeSetExpr (compiled XPath), when evaluated with a contextNode and an ExpressionContext, yields a NodeIterator
NumberExpr
PathPattern	a compiled XPath expression which has an XSLT match priority
Pattern	an XPATH (XSLT) match pattern
StringExpr	an XPath expression which evaluates to a String

VariableSet
Variant
VariantExpr

Class Summary

AddExpr	a compiled XPath expression (component) that represents the addition of two sub-expressions
AlternativesPattern	represents an "OR" (union) of match patterns
AncestorAxisExpr	an XPath expression component representing an ancestor axis
AncestorOrSelfAxisExpr	An XPath expression component representing the ancestor-or-self axis
AncestorsOrSelfNodeIterator	an Iterator that walks toward thwe document root
AndExpr
AnyElementOrAttributeTest
AppendExpr	Represents the concatenation of two String Expressions
ArrayNodeIterator
AttributeAxisExpr
AttributeTest	A compiled XPath component that tests a node to see if it is an attribute with a (possibly?) specified name
AxisExpr
BooleanFunction	a single argument XPath function which casts its argument to a boolean Function: boolean boolean(object)
BooleanRelationalExpr
BooleanVariant	a boolean which can provide its value as a String, Number or Object
CeilingFunction	the XPath Function: number ceiling(number) The ceiling function returns the smallest (closest to negative infinity) number that is not less than the argument and that is an integer.
ChildAxisExpr
CloneableNodeIteratorImpl
CloneableNodeIteratorImpl.NodeList
ComposeExpr	an expression which composes two sub-expressions (for each node in expr1, evaluate expr2)
ConcatFunction	represents the XPath Function: string concat(string, string, string*) has the method makeCallExpr which will construct a String expression representing the concat function
ContainsFunction	Represents the XPath Function: boolean contains(string, string) The contains function returns true if the first argument string contains the second argument string, and otherwise returns false.
Converter
ConvertibleBooleanExpr	An expression which is a boolean, but depending on its use, may be converted to a Number, String or Object
ConvertibleExpr	An XPath expression (component) which can be cast to any of several types as needed
ConvertibleNodeSetExpr	A compiled XPath pattern component which returns a Node set, but is convertible (castable) to a String expression, boolean expression or VariantExpression
ConvertibleNumberExpr
ConvertibleStringExpr
ConvertibleVariantExpr
CountFunction	Represents the XPath Function: number count(node-set) The count function returns the number of nodes in the argument node-set.
CurrentFunction	Represents the XSLT Function: node-set current() The current function returns a node-set that has the current node as its only member.
DecodeURIFunction	Represents the EXSL str:encode-uri function For more information consult exsl specification at: Specification.
DelegateExprContext	a base class for ExprContext classes that override some methods of an existing ExprContext, and delegate the rest of 'em to that existing ExprContest
DescendantAxisExpr	XPath expression (component) representing descendant axis
DescendantOrSelfAxisExpr	an XPath expression "//"
DescendantsOrSelfNodeIterator	walks an entire (sub)-tree, excluding attributes
DifferenceFunction	James Clark's extension function: node-set xt:difference(node-set, node-set)
DifferenceNodeIterator
DivideExpr
DocumentFunction	represents the XSLT Function: node-set document(object, node-set?) The document function allows access to XML documents other than the main source document.
DocumentOrderComparator
ElementAvailableFunction	the XSLT function 'element-available("qname")'
ElementOrAttributeTest
ElementTest	A compiled XPath expression (component) tests a node for being an ELEMENT with a given Name
EmptyVariableSet
EncodeURIFunction	Represents the EXSL str:encode-uri function For more information consult exsl specification at: Specification.
